Can't help you with a known source, but
 

The model number of the magazine is CAA-355-600. The last one I bought was on ebay for $29.95 6 years ago. I think you can get the whole player with a magazine for not much more.

They are not unique to Chevy and you only have to worry about the CAA-355 part of the number. I know Ford used the same unit. That will let you search better.

Here is a website that says they have one.
